Trees growing out of large boulders are always a photographic target . Particularly with a LOT trees growing out of boulders. On the crest of this backcountry ridge, this is a sand tube area where sand was compressed into an elongated sphere early on when it was first buried but still soft and wet. This is ALL Hell Creek Sandstone which routinely flows around internally a bit like soft putty. Sort of like squeezing a tooth paste tube. . This leaves these relatively harder boulders for me to enjoy as they resist weathering better than the material around them.
Deposited in the Cretaceous era about 66 million years old as an age. That lichen can be 100 years or more old. Only rocks that are undisturbed have big lichen patches. Cattle pressure/wear from rubbing will destroy it. This boulder is way out there remote. Not a lot of people have been to this spot. I see wonderful sunsets from here.
Big areas of this boulder strewn surface covered with Sunburst Liichen (Xanthoria sp.) exists here. Called pincushion lichen by some. Bear in mind that there are hundreds of different species of Lichen that inhabit Wyoming and differentiating them exactly is sort of a science all by itself. Lichenologists have to have work of some kind. Academia is the obvious job path. I suspect that there is a use for court testimony however the job prospects of a Lichenologist is about the same as a masters in biostratigraphy such as myself. Though interestingly, biostratigraphers do a lot of work with oil companies .. My general comment about Lichen nomenclature is that you need a bachelors of science in Biology (which I have) to look at the photos. The text about the lichen is a foreign language.😀😀.
Yup, a Tyrannosaurus tooth sitting in the matrix. Wrapping it up for the trip back to the ranch headquarters is the next order of business. There it will be cleaned at my leisure when I get a pile of such things to clean so it’s worth setting up the micro-air-abrasive fossil cleaning cabinet. The black enamel of the tooth is etch by tiny rootlets that covered the surface. The chemical reactions at the rootlets deeply marked the enamel of the tooth.
Fossil Teeth: Selective preservation…
Teeth were “plentiful with many per dinosaur. They often broke off, the new ones erupting from below. Shed teeth were called spitters.They were literally spit out or lost eating. Some teeth passed through the digestive system. Quaintly named (sh**ers) by collectors. I’ve been told by older and more experienced paleontologists the way you tell the difference is their taste…… 😜
Here pictured next to the 6 inch wood awl that I used to dig it out of the Hell Creek/Lance Formation quarry wall. I have a 50 foot long by 4 feet thick in the center, river channel filled with mixed debris. This debris was dropped by the river for a reason. The current velocity dropped enough to leave what it carried here, behind. The bigger/heavier things came out first so we find a lot of big bones. The little things concentrated somewhere else with a lower current velocity.

Enjoying a sunset while walking around with several cameras in the remote backcountry is similar to a shooting gallery with a .22 but without the report. Lots of good stuff to shoot at. Just a click versus bang. BTW, I do carry a firearm in the backcountry. add a few more pounds. You never know exactly what your going to run into. A 10mm 1911 pistol with a 5 inch barrel is good for 300 yards… (work on that one for a while). This was taken this fall and it was pretty chilly.
Boy this sure looks like a fossil horn on a Bison head laying on it’s side.. It’s big and heavy. Those lichens are really old. Hummm I’m SURE that a cowboy or two has roped this over the decades lolol.
Rocks take on many (infinite) shapes due to differential weathering. Soft sediments like wet sand can flow as toothpaste from a tube into surrounding formations. When you put a 10 foot thick layer of heavy mud on top of a few feet of wet sand. This sand is the kind that would squish between your toes. You will get some mixing of the sand into the mud . It’s called “Soft sediment Deformation”. All sorts of exotic Shapes are formed. I’ve seen so many posted on the internet. I’ve got several dozen good examples but this is the biggest one. Yup, must be a fossil bison……. NOT.
Rocks that look like fossils but aren’t are called “Pseudofossils”. Wyoming/Montana has it’s share of real fossils and Pseudofossils. Don’t be fooled by shape. THere has to be substance , 3-d depth to a fossil. Biologic structures are not limited to the surface. You should be able to see “depth” to structure. This “fossil bison” is lacking in any other feature than a “Horn” sticking up and a general shape. Our minds tend to see order in random shapes so we attribute the “fossil Status” on the rock.
So it is a Pseudofossil (fake fossil). I will over time post more of them as I actually collect them and take photos side by side with the real thing. Shape does not make a fossil. There is no substance to a shape in and of itself.
I had turned over this big boulder of Tiger Chert (kinda rare) out by a building leading to this little Black Widow Hunting (me about then) . The boulder of Tiger Chert about 90 pounds (I carried it down a pretty good mountain in a frame pack…. I know lol). So you reach under it to tip it over right?…… Up here you reach under it with gloves on and here is one (just one) of the reason why. Working bare handed turning anything over in Wyoming/Montana is not necessarily the right thing to do lolol.
This Black Widow hunting on Tiger Chert had another agenda than I did. I wonder if it’s like the ground hog and we’re in for an early winter if it see’s it’s shadow? I’m pretty sure it saw that shadow…. Well I know for a fact this gal now resides in an escape proof glass terrarium down in my green house now where she is going to be in a few photosessions I hope. She gets fed a cricket or so a week from the green houses endless supply of crickets lolol. Ultra macro work on her might just be an interesting time spent with a camera dead winter .
Tiger Chert for Rockhounders
As you might expect, the rock is exotic. Oil Chert or Tiger Chert is a fairly rare variety of Silicate mineral.. Named for the alternating bands of light and darker browns or tans, the banding reflects the yearly deposition of sediment into the bottom of prehistoric Lake Gosiute. Outcrops of the material usually occur south and west of Rock Springs as well as a few other places in the Green River Basin. I found this WAY north and east of Dubois Wyoming so this one is an outlier. It was up high when I found it too. Big effort to retrieve it and it still follows me around.
The concoidal fracture and homogenous nature of Tiger Chert made it a favorite of flint nappers throughout the period of human habitation in North America. It occurs in archaeological sites of all ages. It’s beautifully banded, reminds me of tree rings but those were yearly mudstone lake sediments that were literally “replaced” by silicious chert in the diagenetic history of the rock deep in the Wind River Ranges. Many mis-identify it as petrified wood. It’s very similar in composition with most petrified wood but it didn’t used to be wood 🤔
Moon on the Rocks is a capture off the top of a local butte. Capturing the Moon and terrestrial objects in the same focal plain is a hobby of mine as I’ve said before. I only get roughly 2 days a month of this opportunity so 24 days a year at best. Usually the weather doestn’ cooperate and seldom is the seeing so good as to have the details sharp so low in the atmosphere. That old atmospheric lens distorts the details so readily, nights like this are a gift to me. No haze, no distortion and a rock outcrop far enough away AND at the right angle….Click !!!
Moon shot Photographic Musings: Taking an image like this is an exercise in getting distance and topography to line up for you. Distance from the hills is a big deal….. Your working your camera on Manual now right?? 🙏 Highest f-stop on the lens is your first setting. (your priority). High fstop gives you a Chance at focusing both the terrestrial Hill top AND the moon in the same image. Deep focus is the only way to do this.. Your other two settings ISO and shutter speed are easy since you set your shutter speed next to the maximum you can hold the camera steady at say 1/30th of a second for a rested camera and your holding the body or use a tripod (be quick cause the moon moves). Tripod moon shots can be a second long (unless your tracking) with the moon if you have a very high fstop and a low ISO (camera sensitivity). The ISO is the last thing you adjust to bring your image into view and ideally into perfection. Mirrorless cameras are easier than DSLR’s to figure this out with so if your just starting with cameras and your buying, buy a mirrorless. You get to see your settings work live real time before you click unlike a modern DSLR camera that you look at the image you just took AFTER the click. No direct light path to the eye as your looking at a video screen inside the camera. You now know all I know about this 🤔
I hope your Monday is going well. I’ve been on computer since 5AM😎…. Mixed Skies but sunrise looks to be a clear sky (boring) sunrise so I’ll stay in and do digital darkroom work (12 degrees outside).
Perspective is indeed Everything. #3 Rock Shelter and similar images are done with a REALLY wide angle close focus lens. It’s a little tricky to do at times but properly framed, these winter images are simple subjects with spectacular perspective. (January 2019)
It is snowing here at the Bliss Dinosaur Ranch this morning. We have at least 1/2 an inch on the ground and it’s still coming down hard here pre-dawn. It’s still early….But deep in the winter when I can’t get around so easily in the backcountry, I literally have to plow a couple of miles of two track road to get up on this ridge.
Stay tuned for more of these being “refinished to my current standards. My posts will be mix and match for the next few months to populate the new gallery we’re building with my portfolio. Only 5K more images to go…. 🤣
Happy Oct 1…. Holy cow where did the summer go… ?. 🙂 Be safe out there. New post every 3 hours.
I Found this small natural , a cave with a view as it were…. on my place a few years ago. I don’t get a chance to crawl do deeply into it much though. I just be loosing weight :). It is a favorite haunt of rabbits, snake and other critters trying to keep hidden.
